The President of the United States, John F. Kennedy (left) and the Prime Minister of the United Kingdom, Harold Macmillan (right) in Bermuda on 21 December 1961

The Nassau Agreement, concluded on 21 December 1962, was an agreement negotiated between President of the United States, John F. Kennedy, and Harold Macmillan, the Prime Minister of the United Kingdom, as a result of a series of meetings by the two leaders over three days in the Bahamas following Kennedy's announcement of his intended cancellation of the Skybolt. The agreement ended the Skybolt crisis and enabled the UK Polaris programme.

Under an earlier agreement, the US had agreed to supply Skybolt, an American air-launched ballistic missile, in return for the UK allowing the Americans to establish a ballistic missile submarine base in the Holy Loch near Glasgow. The British government had then cancelled the development of its medium-range ballistic missile, known as Blue Streak, leaving Skybolt as the basis of the UK's nuclear deterrent in the 1960s. Without Skybolt, the V-bombers of the Royal Air Force (RAF) would likely become obsolete through being unable to penetrate the improved air defences that the Soviet Union was expected to deploy by the 1970s.

At Nassau, Macmillan rejected Kennedy's other offers, and pressed him to supply nuclear-capable Polaris submarine-launched ballistic missiles. These represented more advanced technology than Skybolt, and the US was not inclined to provide them except as part of a Multilateral Force within the North Atlantic Treaty Organisation (NATO). Under the Nassau Agreement the US agreed to provide the UK with Polaris. The agreement stipulated that the UK's Polaris missiles would be assigned to NATO as part of a Multilateral Force, and could be used independently only when "supreme national interests" intervened.

The Nassau Agreement became the basis of the Polaris Sales Agreement, a treaty which was signed on 6 April 1963. Under this agreement, British nuclear warheads were fitted to Polaris missiles. As a result, responsibility for Britain's nuclear deterrent passed from the RAF to the Royal Navy.

The President of France, Charles de Gaulle, cited the Nassau Agreement as one of the main reasons for his veto of Britain's application for admission to the European Economic Community (EEC) on 14 January 1963.

Background

British nuclear deterrent

During the early part of the Second World War, Britain had a nuclear weapons project, codenamed Tube Alloys.[1] At the Quebec Conference in August 1943, the Prime Minister, Winston Churchill and the President of the United States, Franklin Roosevelt, signed the Quebec Agreement, which merged Tube Alloys with the American Manhattan Project to create a combined British, American and Canadian project.[2] The British government trusted that the United States would continue to share nuclear technology, which it regarded as a joint discovery, after the war,[3] but the United States Atomic Energy Act of 1946 (McMahon Act) ended technical cooperation.[4] Fearing a resurgence of United States isolationism, and Britain losing its great power status, the British government restarted its own development effort,[5] now codenamed High Explosive Research.[6] The first British atomic bomb was tested in Operation Hurricane on 3 October 1952.[7][8] The subsequent British development of the hydrogen bomb, and a favourable international relations climate created by the sputnik crisis, led to the McMahon Act being amended in 1958, resulting in the restoration of the nuclear Special Relationship in the form of the 1958 US–UK Mutual Defence Agreement, which allowed Britain to acquire nuclear weapons systems from the United States.[9]

Avro Vulcan B.1A bomber

Britain's nuclear weapons armament was initially based on free-fall bombs delivered by the V-bombers of the Royal Air Force (RAF), but the possibility of the manned bomber becoming obsolete by the late 1960s due to improvements in anti-aircraft defences was foreseen.[10] In 1953, the Assistant Chief of the Air Staff (Operational Requirements), Air Vice Marshal Geoffrey Tuttle, requested a specification for a ballistic missile with 2,000-nautical-mile (3,700 km; 2,300 mi) range,[11] and work commenced at the Royal Aircraft Establishment in Farnborough later that year.[12] At a North Atlantic Treaty Organization (NATO) meeting in Paris in December 1953, United States Secretary of Defense, Charles E. Wilson, raised the possibility of a joint medium-range ballistic missile (MRBM) development programme. Talks were held in June 1954, resulting in the signing of an agreement on 12 August 1954.[11][10] The United Kingdom with United States support would develop an MRBM of 2,000-nautical-mile (3,700 km) range.[11][13] This was called Blue Streak.[10] It was initially estimated to cost £70 million, with the United States paying 15 per cent.[14] By 1958, the project was in trouble. Its deployment was still years away, but the United States was supplying American-built Thor intermediate-range ballistic missiles under Project Emily, and there were concerns about liquid fuelled Blue Streak's vulnerability to a pre-emptive nuclear strike.[15][16]

To extend the effectiveness and operational life of the V-bombers, an Operational Requirement (OR.1132), was issued on 3 September 1954 for an air-launched, rocket-propelled standoff missile with a range of 100 nautical miles (190 km; 120 mi) that could be launched from a V-bomber. This became Blue Steel. The Ministry of Supply placed a development contract with Avro in March 1956, and it entered service in December 1962.[17] By this time it was anticipated that even with Blue Steel, the air defences of the Soviet Union would soon improve to the extent that V-bombers might find it difficult to attack their targets, and there were calls for the development of the Blue Steel Mark II with a range of at least 600 nautical miles (1,100 km; 690 mi).[18] Despite the name, this was a whole new missile, and not a development of Mark I.[19] The Minister of Aviation, Duncan Sandys, insisted that priority be accorded to getting the Mark I into service,[18] and the Mark II was cancelled at the end of 1959.[19]

Skybolt

Confronted with the same problem, the United States Air Force (USAF) also attempted to extend the operational life of its strategic bombers by developing a stand off missile, the AGM-28 Hound Dog.[20] The first production model was delivered to the Strategic Air Command (SAC) in December 1959. It carried a 4-megatonne-of-TNT (17 PJ) W28 warhead, and had a range of 642 miles (1,033 km) at high level and 340 miles (550 km) at low level. Its circular error probable (CEP) of over 1 nautical mile (1.9 km; 1.2 mi) at full range was considered acceptable for a warhead of this size. A Boeing B-52 Stratofortress could carry two, but the underslung Pratt & Whitney J52 engine precluded its carriage by bombers with less underwing clearance like the Convair B-58 Hustler and the North American XB-70 Valkyrie. It entered service in large numbers, with 593 in service by 1963. Numbers declined thereafter to 308 in 1976, but it remained in service until 1977, when it was replaced by the AGM-69 SRAM.[21] Despite its being superior in performance to Blue Steel, the British showed little interest in Hound Dog. It could not be carried by the Handley Page Victor, and there were doubts as to whether even the Avro Vulcan had sufficient ground clearance.[22]

Even as Hound Dog was entering service, the USAF was contemplating a successor. An Advanced Air to Surface Missile (AASM) that could carry a 0.5-to-1.0-megatonne-of-TNT (2.1 to 4.2 PJ) warhead with a range of 1,000 to 1,500 nautical miles (1,900 to 2,800 km; 1,200 to 1,700 mi) and a CEP of 3,000 feet (910 m). Such a missile would make manned bombers competitive with Intercontinental Ballistic Missiles (ICBMs). However, it would also require significant technological advances. The missile became the AGM-48 Skybolt. As costs rose and support diminished, the USAF decreased its specifications to carrying a warhead 600 to 1,000 nautical miles (1,100 to 1,900 km; 690 to 1,150 mi) and a CEP of 1.5 nautical miles (2.8 km; 1.7 mi). This was estimated to cost $893.6 million. A May 1960 report to George Kistiakowsky, the chairman of the President's Science Advisory Committee (PSAC), by the PSAC Missile Advisory Panel was unconvinced of the Skybolt's merits, as the new LGM-30 Minuteman ICBM would be able to perform the same missions at much lower cost. PSAC therefore recommended in December 1960 that Skybolt be cancelled forthwith. United States Secretary of Defense Thomas S. Gates, Jr., elected not to request further funding for it, but avoided cancellation by reprogramming $70 million from the previous year's allocation.[23]

A crucial reason for Skybolt's survival was the support it garnered from Britain.[23] Blue Streak was cancelled on 24 February 1960, subject to an adequate replacement being procured from the US. An initial solution appeared to be Skybolt, which combined the range of Blue Streak with the mobile basing of the Blue Steel, and was small enough that two could be carried on the Vulcan bomber.[24] Armed with a British Red Snow warhead, this would improve the capability of the UK's V-bomber force, and extend its useful life into the late 1960s and early 1970s.[25] Like the USAF, the RAF was concerned that ballistic missiles could eventually replace manned bombers.[26] An institutional challenge came from the United States Navy, which was developing a submarine-launched ballistic missile (SLBM), the UGM-27 Polaris. The US Chief of Naval Operations, Admiral Arleigh Burke, kept the First Sea Lord, Lord Mountbatten, apprised of its development.[27] By moving the deterrent out to sea, Polaris offered the prospect of a deterrent that was invulnerable to a first strike, and reduced the risk of a nuclear strike on the British Isles.[28] The British Nuclear Deterrent Study Group (BNDSG) produced a study that argued that SLBM technology was as yet unproven, that Polaris would be expensive, and that given the time it would take to build the boats, it could not be deployed before the early 1970s.[29] The Cabinet Defence Committee approved the acquisition of Skybolt in February 1960.[30]

The Prime Minister, Harold Macmillan, met with President Dwight Eisenhower, at Camp David near Washington in March 1960, and secured permission to buy Skybolt without strings attached. In return, the Americans were given permission to base the US Navy's Polaris-equipped ballistic missile submarines at the Holy Loch in Scotland.[31] The financial arrangement was particularly favourable to Britain, as the US was charging only the unit cost of Skybolt, absorbing all the research and development costs.[25] Mountbatten was disappointed, as was Burke, who now had to face the possible survival of Skybolt at the Pentagon.[30] Exactly what was agreed with regard to Polaris was not clear; the Americans wanted any later offer of Polaris to be as part of a scheme for deployment of NATO MRBMs known as the Multilateral Force.[32] With the Skybolt agreement in hand, the Minister of Defence, Harold Watkinson, announced the cancellation of Blue Streak to the House of Commons on 13 April 1960.[24]

American concerns

Skybolt proponents in the USAF hoped that the incoming Kennedy administration, which took office in January 1961, would be supportive of Skybolt, given its election campaigning on the basis of an alleged missile gap between Soviet and US capabilities.[33] Initially it was; Robert McNamara the new Secretary of Defense, defended Skybolt before the Senate Armed Services Committee.[34] He requested $347 million to purchase 92 Skybolt missiles in 1963, with the intention of deploying 1,150 missiles by 1967.[35] However, on 21 October 1961 the USAF raised its estimate of research and development costs to $492.6 million, an increase of over $100 million, and production costs were now reckoned at $1.27 billion, an increase of $591 million.[36]

US Secretary of Defense Robert McNamara in 1967

The Kennedy Administration adopted a policy of opposition to independent British nuclear forces in April 1961.[37] In a speech at Ann Arbor, Michigan, on 16 June 1962, McNamara stated "limited nuclear capabilities, operating independently, are dangerous, expensive, prone to obsolescence and lacking in credibility as a deterrent," and that "relatively weak national nuclear forces with enemy cities as their targets are not likely to perform even the function of deterrence."[38] Dean Acheson was even more blunt; in a speech at West Point he stated: "Britain's attempt to play a separate power role – that is, a role apart from Europe, a role based on a 'special relationship' with the United States, a role based on being the head of a Commonwealth which has no political structure or unity or strength and enjoys a fragile and precarious economic relationship – this role is about played out."[39]

The Kennedy administration was concerned that a situation like the Suez Crisis might repeat itself, one that would once again incite a response from the Soviets.[40] The Americans developed a plan to force the UK into the Multilateral Force concept, a dual key arrangement that would only allow launch if both parties agreed. If those weapons were part of a single larger force, attacking them would require attacks on the other hosting countries as well, making the prospect far less interesting. The US also feared that other countries would want to follow the UK lead and develop their own deterrent forces, leading to a proliferation problem even among their own allies. If a deterrent was being provided by a larger international force, the need for individual forces would be reduced.[41][42]

Between 1955 and 1960, the British economy had lagged behind that of the rest of Europe, growing at an average of 2.5 per cent per annum, compared with France's growth of 4.8 per cent, Germany's of 6.4 per cent, and the European Economic Community (EEC) average of 5.3 per cent. It was clear that Britain's economic future lay in Europe and becoming a member of the EEC, and Macmillan devoted much of 1960 to laying the ground for Britain's entry into the EEC.[43] The US was concerned that providing Polaris to Britain would jeopardise Britain's prospects of joining the EEC.[44] Long-term US policy was to persuade the UK to build up its conventional military forces, and to secure admission to the EEC.[45]

McNamara introduced cost-effectiveness analysis to defence procurement. Skybolt suffered from rising costs,[42] and the first five test launches were failures. This was not unusual; Polaris and Minuteman had similar problems.[46] What doomed Skybolt was an inability to demonstrate capability beyond that achievable by Hound Dog, Minuteman or Polaris.[42] This meant that there were few advantages for the United States in continuing Skybolt,[47] but at the same time its cancellation would be a powerful political tool for bringing the UK into their Multilateral Force.[42] The British, on the other hand, had cancelled all other projects to concentrate fully on Skybolt. When warned not to put all their eggs in the one basket, the British replied that there was "no other egg, and no other basket".[47] On 7 November 1962, McNamara met with Kennedy, and recommended that Skybolt be cancelled. He then briefed the British Ambassador to the United States, David Ormsby-Gore. Kennedy agreed to cancel Skybolt on 23 November 1962.[46]

Negotiations

McNamara met with Solly Zuckerman, the Chief Scientific Adviser to the Ministry of Defence on 9 December, [48] and flew to London to meet with the Minister of Defence, Peter Thorneycroft, on 11 December.[49] On arrival he told the media that Skybolt was an expensive and complex program that had suffered five test failures.[50] Kennedy told a television interviewer that "we don't think that we are going to get $2.5 billion worth of national security".[51] US National Security Advisor McGeorge Bundy gave an interview on television in which he stated that the US had no obligation to supply Skybolt to the UK.[52] Thorneycroft had expected McNamara to offer Polaris instead, but found him unwilling to countenance such an offer except as part of a Multinational Force. McNamara was willing to supply Hound Dog, or to allow the British to continue development of Skybolt.[49]

These discussions were reported to the House of Commons by Thorneycroft,[53] leading to a storm of protest. Air Commodore Sir Arthur Vere Harvey pointed out that while Skybolt had suffered five test failures, Polaris had thirteen failures in its development. He went on to state "that some of us on this side, who want to see Britain retain a nuclear deterrent, are highly suspicious of some of the American motives... and say that the British people are tired of being pushed around".[53] Liberal Party leader Jo Grimond asked: "Does not this mark the absolute failure of the policy of the independent deterrent? Is it not the case that everybody else in the world knew this, except the Conservative Party in this country? Is it not the case that the Americans gave up production of the B52, which was to carry Skybolt, nine months ago?"[53]

As the Skybolt crisis came to the boil in the UK, an emergency meeting between Macmillan and Kennedy was arranged to take place in Nassau, Bahamas. Accompanying Macmillan were British Secretary of State for Foreign and Commonwealth Affairs, Lord Home; Thorneycroft; Sandys; and Zuckerman. Naval expertise was supplied by Vice Admiral Michael Le Fanu.[54] Ormsby-Gore flew to Nassau with Kennedy. En route, he brokered a deal whereby Britain and the United States would continue development of Skybolt, with each paying half the cost, the American half being a kind of termination fee.[55] In London, over one hundred Conservative members of Parliament, nearly one third of the parliamentary party, signed a motion urging Macmillan to ensure that Britain remained an independent nuclear power.[56]

Talks opened with Macmillan detailing the history of the Anglo-American Special Relationship, going back to the Second World War. He rejected the deal that Kennedy and Ormsby-Gore had reached. It would cost Britain about $100 million, and was not politically viable in the wake of recent public comments about Skybolt.[57] Kennedy then offered Hound Dog. Macmillan turned this down on technical grounds, although it had not been subjected to a detailed assessment, and probably would have worked for the RAF into the 1970s, as it did for the USAF.[58]

It therefore came down to Polaris, which the US did not wish to supply except as part of a Multinational Force. Macmillan was emphatic that he would commit the submarines to NATO only if they could be withdrawn in case of a national emergency. When pressed by Kennedy as to what sort of emergencies he had in mind, Macmillan mentioned the Soviet threats at the time of the Suez crisis, Iraqi aggression against Kuwait, or a threat to Singapore. The British nuclear deterrent was not just for deterring attacks on the UK, but to underwrite Britain's role as a great power.[40] In the end, Kennedy did not wish to see Macmillan's government collapse,[59] which would imperil Britain's entry into the EEC,[60] so a face-saving compromise was found, which was released as a joint statement on 21 December 1962:

These forces, and at least equal US Forces, would be made available for inclusion in a NATO multilateral nuclear force. The Prime Minister made it clear that except where HMG [Her Majesty's Government] may decide that supreme national interests are at stake, these British forces will be used for the purposes of international defense of the Western Alliance in all circumstances.[61]

On 22 December, after the Nassau conference had ended, the USAF conducted the sixth and final test flight of Skybolt, having received explicit permission to do so from Roswell Gilpatric, the United States Deputy Secretary of Defense, in McNamara's absence. The test was a success.[50] Kennedy was furious, but Macmillan remained confident that the Americans had "determined to kill Skybolt on good general grounds—not merely to annoy us or drive Great Britain out of the nuclear business".[62] The successful test raised the possibility that the USAF might get the Skybolt project re-instated, and the Americans would renege on the Nassau Agreement.[62] This did not occur; Skybolt was officially cancelled on 31 December 1962.[50]

Outcome

Macmillan placed the Nassau Agreement before the cabinet on 3 January 1963. He made the case for Britain retaining nuclear weapons. He asserted that it would not be in the best interest of the Western Alliance for all knowledge of the technology to reside with the United States; that possession of an independent nuclear capability gave Britain the ability to respond to threats from the Soviet Union even when the United States was not inclined to support Britain; and that possession of nuclear weapons gave Britain a voice in nuclear disarmament talks. However, concerns were expressed that the dependence on the United States would necessarily diminish Britain's influence on world affairs. Thorneycroft addressed the view that Britain should provide a nuclear deterrent from its own resources. He pointed out that Polaris represented $800 million in research and development costs that the United Kingdom would save. Nonetheless, the Chancellor of the Exchequer, Selwyn Lloyd, was still concerned at the cost.[63]

In the wake of the Nassau Agreement, the two governments negotiated the Polaris Sales Agreement, a treaty under the terms of which the US supplied Polaris missiles,[64] which was signed on 6 April 1963.[65] The missiles were equipped with British warheads.[66][67] The UK retained its deterrent force, although its control passed from the RAF to the Royal Navy.[68] Polaris was a better weapon system for the UK's needs, and has been referred to as "almost the bargain of the century",[69] and an "amazing offer".[70] The V-bombers were immediately reassigned to NATO under the terms of the Nassau Agreement, carrying tactical nuclear weapons,[71] as were the Polaris submarines when they entered service in 1968.[72] The Polaris Sales Agreement was amended in 1980 to provide for the purchase of Trident.[73] British politicians did not like to talk about "dependence" on the United States, preferring to describe the Special Relationship as one of "interdependence".[74]

As had been feared, the President of France, Charles de Gaulle, vetoed Britain's application for admission to the EEC on 14 January 1963, citing the Nassau Agreement as one of the main reasons. He argued that Britain's dependence on United States through the purchase of Polaris rendered it unfit to be a member of the EEC.[75] The US policy of attempting to force Britain into their Multilateral Force proved to be a failure in light of this decision, and there was a lack of enthusiasm for it from the NATO allies, particularly Britain. By 1965, the Multilateral Force began fading away. The NATO Nuclear Planning Group gave NATO members a voice in the planning process without full access to nuclear weapons. The Standing Naval Force Atlantic was established as a joint naval task force, to which various nations contributing ships rather than ships having mixed crews.[76]

Macmillan's government lost a series of by-elections in 1962,[77] and was shaken by the Profumo affair in 1963.[78] In October 1963, on the eve of the annual Conservative Party Conference, Macmillan fell ill with what was initially feared to be inoperable prostate cancer.[79] His doctors assured him that it was benign, and that he would make a full recovery, but he took the opportunity to resign on the grounds of ill-health.[80] He was succeeded by Lord Home, who renounced his peerage and as Alec Douglas-Home campaigned on Britain's nuclear deterrent in the 1964 election.[81] While the issue was of low importance in the minds of the electorate, it was an issue on which Douglas-Home felt passionately, and on which the majority of voters supported his position.[82] The Labour Party election manifesto called for the Nassau Agreement to be renegotiated, and on 5 October 1964, the leader of the Labour Party, Harold Wilson, criticised the independent British deterrent as neither independent, nor British, nor a deterrent.[82] Douglas-Home narrowly lost the election to Wilson.[83] In office, Labour retained Polaris,[84] and assigned the Polaris boats to NATO, in accord with the Nassau Agreement.[85]

Kennedy, stung by the entire issue, commissioned a detailed report by Richard Neustadt on the events and what lessons could be learned from them. Jacqueline Kennedy Onassis recalled him reading the initial report and commenting that "If you want to know what my life is like, read this."[86] The report was declassified in 1992 and published as Report to JFK: The Skybolt Crisis in Perspective.[86]
